Description

Technical Field

[0001] This utility model relates to the field of spindle technology, and in particular to a reversible spindle. Background Technology

[0002] Winding machines are specialized equipment in the textile industry. As the final process in spinning and the first process in weaving, winding plays a crucial "bridge" role, thus holding an important position in the textile field. The main tasks of winding are: first, to change the package shape and increase the yarn capacity of the package; and second, to remove defects on the yarn and improve its quality. The bobbin is the core component of the winding machine. Its main function is to support and drive the yarn during the winding process, ensuring that the yarn can be accurately and stably wound onto the bobbin. Its quality and performance have a significant impact on the working efficiency of the winding machine, the quality of the yarn, and the entire textile production process.

[0003] Currently, there are two types of inverted spindles on the market. One type uses a spindle foot support. This type of rotor has a large yarn storage capacity, but a low rotation speed (4000-6000 rpm) and high power consumption. It requires periodic shutdowns for oil changes, cleaning, and lubrication maintenance of the spindle feet, which can lead to production stoppages and affect production efficiency. The other type uses ball bearings in the inverted spindle bearing assembly. Both types of spindles use a belt drive, which results in low transmission efficiency and inaccurate speed control, thus affecting the quality of the yarn. Utility Model Content

[0004] The purpose of this invention is to provide a novel inverted spindle. This device features bearing maintenance-free operation, high speed, and small amplitude. Since the spindle uses a single-spindle motor drive, the speed control is more precise.
